<p>We all embody various intersecting visible and non-visible social identities. Those intersecting identities can place some individuals at the margins or borderlands of their other identities, causing dissonance and perhaps threatening their sense of belonging to a community. Compounding potential identity dissonances, a learner finding their fit in engineering will likely face engineering attributes such as meritocracy, heteronormativity, and a climate that prioritizes technical feats and dismisses social phenomena as outside the scope of engineering. These interactions can negatively impact their belonging, persistence, and degree</p> <p>completion.</p> <p><br></p> <p>However, completing an arduous engineering degree at the intersection of multiple minoritized identities is feasible. In my dissertation, I use three studies to investigate how gay Latinx engineers navigate the borderlands of their intersecting identities. Along the way, I explore how they bridge the borderlands between those and their engineering identities as I examine how they manifest and leverage their assets at this identity intersection. Initial findings suggest that learners at the borderlands of multiple minoritized identities are keenly aware of social identities and cope by leveraging some of their powerful identities (i.e., masculinity, math, and science identities) to increase their sense of belongingness, proving they are successful and valuable members of humankind.</p>

This thesis involves the creation of a system of embedded touchscreen devices called touchSPICE to aid in the learning of basic circuits. Traditionally, circuit theory is taught to students in two different methods, lectures and laboratory exercises. Lectures focus on auditory and visual learning and are largely passive learning. Lab experiments allow students to physically interact with the circuits, and learn visually through viewing output waveforms from simulators or on measurement devices. The goal of the touchSPICE project is to develop a physical system for virtual, real-time SPICE simulation that mimics the laboratory experience. In touchSPICE, touchscreen devices act as circuit nodes that communicate with immediate neighbors using physical wires. Additionally, the nodes communicate wirelessly with a host computer, running a customized version of SPICE. Data is aggregated on the host computer and plotted in real-time. Changes in configuration of the nodes (component types and values), are then reflected on the host computer’s display. The efficacy of touchSPICE as a learning tool was evaluated by using anonymous surveys from 20 subjects including a pretest, followed by an interactive session with touchSPICE, and a follow-up posttest. Results collected showed that with a few changes to improve the responsiveness of the touchscreen, touchSPICE may be an effective method for teaching circuit theory. Additionally, users enjoyed the quick configuration time that touchSPICE provided, and felt that the real-time feedback of touchSPICE helped support understanding of how circuits operate.

<p dir="ltr">Empathic design involves two social practices – one is collaboration with users to elicit and make a meaning of user experiences, and another is intrateam collaboration to develop a mutually understood, agreed-upon interpretation of user experiences among team members. This study is focused on the latter phenomenon, conceptualizing this social practice as team learning for shared empathic understandings. Through this conceptualization, this study aimed to characterize a social mechanism underlying intrateam collaboration in empathic design in terms of how professionals interact with each other to develop and apply shared empathic understandings to design ideas within a team over a design process. For this objective, I conducted a conversation analysis to examine one professional design team’s conversations over a design journey from need-finding to initial ideation to prototyping and testing, exploring team members’ conversational behaviors revealed in conversational exchanges. More specifically, I investigated their conversational behaviors at both the team and individual levels: team learning behaviors (i.e., construction, co-construction, and constructive conflict) for team-level collective behaviors and interpersonal reactions (e.g., move, question, block, etc.) and empathy perspectives (i.e., the first, second, and third-person perspectives) for individual-level behaviors. Through this investigation, I found that a team’s design journey can be characterized by their travel among the team learning behaviors during design conversations and that each type of team learning behavior can be featured by frequently used interpersonal reactions and empathy perspective transitions at the individual level. Through this behavior-oriented, holistic view of team learning for shared empathic understandings, this study provides fresh insights into what conversational behaviors can be more used at the team and individual levels and how these behaviors can facilitate a team to arrive at team-level empathic understandings and design ideas. I discuss the research and educational implications of this study and future research ideas based on this study.</p>
